From: Categorizing biomedicine images using novel image features and sparse coding representation
Eight examples of image classes used in this paper. Eight image classes and sub-classes in our image taxonomy, which are organized as a two-level class hierarchy. On the top level, images are categorized into the classes of flow charts, experimental images, graph images, mix images, and others. On the bottom level, images are further divided into eight categories where the class of experimental images is categorized into microscopy and gel electrophoresis images; the class of graph images into line charts, bar charts, spot charts, and tables.
